That means the linking is being done for a GUI application. I guess you wanted to build a console application, so you should learn what these options for the linker mean: -Wl,-subsystem,console -Wl,-subsystem,windows There are equivalent options used with the compiler g++, I think they are: -mconsole -mwindows In general there are many options that apply only to Windows builds, for instance building Qt GUI applications I use these for the linker: -Wl,-enable-stdcall-fixup -Wl,-enable-auto-import -Wl,-enable-runtime-pseudo-reloc -Wl,-as-needed but they are not for solving linking errors, just to quiet the warnings, and try to optimize the result. -- René Berber -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
